Contexts of drinking and cannabis use by Whites and Hispanics in California

This study examines the contexts in which alcohol and cannabis are used among White and Hispanic co-users in 40 selected cities in California. Data were obtained from a household sample of 1,069 adults aged 21 to 49, collected via an online standardized questionnaire. Alcohol and cannabis use occurred mostly in two primary settings: at home alone or with family and at home with friends. Controlled analyses identified distinct correlates associated with each consumption context. However, race/ethnicity and co-use status (concurrent vs. simultaneous use) did not have statistically significant effects in any drinking or cannabis use setting. While context related differences between White and Hispanic co-users of alcohol and cannabis were minimal, it would be premature to assume that policies to regulate context use, especially public access contexts, would be equally effective across both groups. Although their epidemiological profiles appear similar, tailored intervention strategies—differing in content, format, delivery, and implementation—may be necessary to maximize effectiveness.
